Patent number: 9486395Abstract: The present application provides a synthetic spilanthol flavor composition that includes (2E,6Z,8E)-N-(2-methylpropyl)-2,6,8-decatrienamide. The synthetic spilanthol composition can also contain, and at least one of (2E,6E,8E)-N-(2-methylpropyl)-2,6,8-decatrienamide and (2E,6Z,8Z)—N-(2-methylpropyl)-2,6,8-decatrienamide, the (N-(2-methylpropyl)-2,6,8-decatrienamide being present in amounts effective to impart a salivating or tingle effect while reducing the perception of off notes, as compared to the off-notes perceived upon consumption of natural spilanthol (e.g. spilanthol obtained from jambu oleoresin). Methods of increasing salivation and/or providing a tingling sensation upon consuming an orally consumable product that include adding to the product a synthetic spilanthol flavor composition are also provided.Type: GrantFiled: April 21, 2014Date of Patent: November 8, 2016Assignee: TAKASAGO INTERNATIONAL CORPORATIONInventors: Louis Lombardo, Michael E.
